When we think of relays, we tend to think of those big mechanical things that make a satisfying ‘click’ when activated. As nice as they are for relay-based computers, there are times when you don’t ...

The project is designed for a three phase solid state relay system. It incorporates three single phase units where each phase is controlled individually by a power triac with RC snubber network for ...

One advantage of solid-state relay (SSR) over conventional electro-magnetic relay (EMR) is its tear and wear free operation. S201S01 from Sharp is a good example. Here is the circuit diagram of a DIY ...

THE ISOLAR BX SOLAR SYSTEM CONTROLLER is a multi-functional differential controller that can be used in a wide variety of solar heating applications. It features four relay outputs — three are triac ...

Toshiba Electronic Devices & Storage Corporation has launched TLP3910, a photovoltaic-output photocoupler housed in a thin SO6L package, suitable for driving the gates of high-voltage power MOSFETs ...

Two new triac-output optocouplers developed by Toshiba Electronics Europe provide reinforced insulation and low LED trigger currents up to 3 mA. Two new triac-output optocouplers developed by Toshiba ...
